Abstract
Prediction of nitrification activity using easily measured soil physicochemical factors or readily available geographical factors is a great help for forest management planning. We reviewed previous studies aimed to predict regional variation in nitrification activity. The applicability of multiple regression models depends on the range of nitrification activity, and consequently, the scale of the target area. Although geographical factors, especially nominal ones, were less effective than continuous variables describing soil physicochemical properties, whole watershed-scale variation in nitrification activity was well predicted using only geographical factors. Nominal geographical factors (e.g., soil type, dominant species, and parent material) well represent site environmental conditions that relate to nitrification activity ', however, the resolution of available data concerning the geographical factors is not always sufficient. The use of digital elevation models (DEM) with geostatistical approaches should be promoted to overcome the lack of suitable geographical data resources.
